Abstract

The invention relates to a manufacturing method of a composite plastic conductive electrode and a conductive electrode manufactured by the same. The manufacturing method of the composite plastic conductive electrode comprises the following steps of: A. fully mixing plastic cement particles with a conductive agent, and carrying out hot melting on a mixture under the condition of 180 to 300 DEG C; B. manufacturing a carbonaceous conductive plate with the thickness of 0.5-20mm; C. cooling the carbonaceous conductive plate to 125-150 DEG C, and pressing carbon felts with the thickness of 2-22mm to the inside the carbonaceous conductive plate such that the carbon felts and the carbonaceous conductive plate are integrated; and D. cooling to prepare the composite plastic conductive electrode. The composite plastic conductive electrode comprises at least one carbonaceous conductive plate and at least two second carbon felts, wherein the second carbon felts are pressed into and integrated with the carbonaceous conductive plate into a whole. The composite plastic conductive electrode manufactured by adopting the scheme has remarkably improved conductive performance, compact conductive electrode structure and difficulty of deformation and greatly prolongs the service life of the conductive electrode in a stable state.

Description

【Technical field】 [0001] The invention relates to a conductive electrode for batteries and a manufacturing method thereof, in particular to a composite plastic conductive electrode and a manufacturing method thereof, and belongs to the field of vanadium battery manufacturing. 【Background technique】 [0002] The electrode materials currently used in vanadium batteries are mainly non-metallic electrode plates such as plastic plates and graphite plates. [0003] In practice, it is found that the non-metallic electrode plate has poor conductivity stability during use and is prone to breakage, that is, when the non-metallic electrode is used for a long time, as the electrode temperature rises, its resistance will be at the critical point The sudden increase will cause the electrode to deform and affect the normal use of non-metallic electrodes. Specifically reflected in the plastic electrode plate is poor mechanical performance and poor electrical performance; the graphite plate...
